In the last few years, phthalocyanines have also been intensively
studied as photosensitizers for photodynamic cancer
therapy For this application the most important
property of these tetrapyrrol rings is their solubility in water
over a wide pH range. Especially, cationic water-soluble phthalocyanines
have some advantages over porphyrins in PDT because
of their strong absorbance at long wavelengths of the
visible spectrum as well as their high yield triplet states with
long lifetimes . Cationic phthalocyanines also represent
a large and expanding class of compounds which have applications
in biology, catalysis and materials.
The synthesis of tetrakis-(3-pyridyloxy)phthalocyanines
and tetracationic derivative of zinc phthalocyanine has been
reported . Recently, our group has also reported the synthesis
of an octacationic porphyrazine by quaternization of
the pyridyl- and dimethylaminoethyl-donors ．

在过去的几年中, phthalocyanines亦曾钻研asphotosensitizersforphotodynamic癌症疗法对这种应用最重要财产. 这些tetrapyrrol戒指是他们在水中溶解度较广泛的pH值范围内. 尤其 阳离子水溶性菁有某些优势porphyrins疗法,因为其强大的吸收长波长的 可见光以及他们高产三重态的长寿命. 阳离子酞菁也代表着庞大而扩展类化合物,其中已应用在生物催化和材料. 合成的四-(3-吡啶)phthalocyaninesandtetracationic衍生锌酞已有报导. 最近,我们小组还报道了合成一个octacationicporphyrazine由quaternization的吡啶和甲基-捐助.
